This invention relates to spraying apparatus and is more especially concerned with the nozzle structures of apparatus of this type intended primarily for use in spraying gardens, lawns,

Fig. l is a plan View of an apparatus em bodying this invention;

Fig. 2 is a side elevation, on a larger scale, of the device shown in Fig. 1;

Fig. 3 is a vertical, sectional view taken approximately on the line 33, Fig. 1;

Fig. 4 is a plan view of the nozzle cap and the plunger with which it cooperates; and

Fig. 5 is a view, on a large scale, of a nozzle aperture arrangement sometimes preferred.

Referring first to Figs. 1, 2 and 3, the construction there shown comprises a nozzle body 2 of hollow tubular form mounted, in this instance, on a stand, although it is also adapted for use in a nozzle designed to be held in the hand. Threaded on the upper end portion of the body 2 is a nozzle cap 4. In order to prevent leakage between this cap and the body, the lower or skirt portion of the cap is externally threaded to receive a sleeve 5 which is shouldered internally and a packing 6, Fig. 3, is mounted in the space between the internal shoulder on the sleeve and the lower end of the cap 4. This member 5 forms essentially a packing gland, and after it has been tightened up it may then be secured against rotation relatively to the cap by means of a small screw 1, threaded into a hole formed in the abutting surfaces of the two parts 4 and 5.

Preferably the upper end of the cap 4 is made of conical form and is apertured for the discharge of water or other liquid conducted to it through the body 2. Cooperating with this cap is a hollow plunger 8 fitting snugly, but slidably, within the body 2 and provided with a tapered head, also apertured and normally held in contact with the inner end wall of the cap 4 by means of a coiled spring ID. A pin ll, Fig. 3, anchored in the body 2 and extending into a ver- 2 Claims. (Cl. 299+l44) tical slot in the plunger, prevents rotation of the latter.

So far as the parts above described are concerned, the construction is much like that illustrated in my earlier Patent No. 2,380,518, issued -July 31, 1945. The present invention, however,

differs from my earlier construction in being better adapted for use on a stand. More importantly, however, it involves a novel arrangement of apertures by means of which the spray can be confined to a very small area, When desired; its

direction, when confined to a more or less limited area, can be readily changed by a simple adjustment; and by making a further adjustment a large general area around the stand can be -sprayed. For these purposes an important feature of this invention resides in the arrangement of apertures provided in the .cap 4 and in the cooperating upper end portion of the plunger 8. As best shown in Fig. 4, a circular series of ports, apertures, or orifices I2 is formed through the tapered end portion of the cap 4. Spaced radially inside of this series of apertures is another series I3, concentric with the series l2, but being semi-circular in extent. Also, as clearly shown in said figures, the apertures in the upper series I3 are staggered circumferentially with reference to those in the lower series l2. Both series are centered in th axis of the nozzle body 2.

In the upper end of the plunger 8 two corresponding series of apertures, indicated in Fig. 4 at l2 and I3, respectively, are formed, and these apertures are so spaced that they can all be made to register with the corresponding apertures in the cap. In the particular construction shown there are ten apertures in the outer or lower series and five in the upper series, although this number obviously can be varied within any practical limits desired.-

In using the apparatus, and assuming that water under pressure is supplied to the nozzle structure through the stand 3, it will be evident that if all the apertures in the plunger and cap are in register, then a large area immediately surrounding the stand will be sprayed. If, now, it is desired to reduce the volume of the spray, that can be done by turning the cap 4 approximately which will shut oil the water completely from the upper holes 13 in the cap. This result is produced because a non-perforated area of the cap is covering all of the five upper holes I3 in the head of the plunger.

However, starting from this position, if the cap is turned counter-clockwise, Fig. 4, slowly, the first hole a in the upper row I3 will soon be brought into register with the end hole I) in th upper row in the plunger 8. Because the inner or upper holes are staggered with reference to those in the lower or outer series, the water is now shut off from all of the latter holes and a single stream only of water can escape through the registered holes a and 12. Thus a very small area only-bis sprayed, say a single bush,

If the cap iisfgiven a runner eoq t rgc qcgwg rotative movement sufiicient to bring the second hole in the series [3 into register with the hole b, the aperture a, then will bebrought into register with the second hole at lithe pmeger. two streams of water will be directed through these two pairs of registered ap ertures butthe. Water will be shut oil from all of the other holes.

By making further step-by-st'ep counter-clockwise adjusting movements of the cap 4, additional holes in the upper series +3 of the plunger'can be brought into. register, one at a time, withthe holes i3, hate all 'five bf them are discharging w Thus one or all, or any intermediate number of V thecodperating;apertures in the upper series 'li can be made to discharge water, asdeand the "area'that will be sprayed will 'be, spondingly. changed.
